PR6423/03R-012-ZD is an Emerson EPRO PR6423 eddy-current displacement sensor configuration. The PR6423 family measures static and dynamic shaft displacement without contact and is used for radial vibration, axial position, eccentricity, differential expansion, valve position and air-gap measurement.

PR6423 systems use a compatible CON converter and a matched cable path. The /03R-012-ZD suffix must remain intact because it defines the mechanical and connection configuration; those details should be verified from the exact sensor label and project documentation.

• Measures shaft motion and position directly through the bearing arrangement.
• Supports both protection and condition-monitoring applications on sleeve-bearing machinery.
• Works with dedicated CON signal converters as a complete transducer system.
• Retains the exact suffix needed for probe geometry, cable and connection control.

• Match the complete PR6423/03R-012-ZD label, mounting geometry and cable system.
• Confirm CON converter type, calibrated system length, target material and monitor input.
• Verify probe gap, bracket stiffness, thread or holder, cable routing and connector form.
• Do not interchange PR6423 suffixes solely because the sensing tip looks similar.

• Record probe label, converter label, cable sections, total system length and installed gap voltage.
• Protect the tip and cable from impact, tight bends and connector contamination.
• After installation, set mechanical gap, verify linear response and polarity, and establish a new vibration baseline.
